Whoa!
Sad to see a Piggy go, but I guess all things go.
Thanks for be willing to document the tank anatomy for science! What year gas tank is this?
 
1976 FJ55 Gas tank Nipples All on top of tank , The red is fuel intake , all the gray lines are vent lines in all corners . Also the fuel return line is just that short Nipple by the red intake ,

:oops::oops::oops::oops::oops::oops:

Somebody might want to save this ????

This is great, 'cept I am trying to picture where the fuel suction line begins on the floor of the tank?
Did y'all cut part of the bottom off?
How does the fuel supply line transition from bottom to top of tank?
Thanks!
 
Question for the group... Is it all that important to have four vent lines or would two be enough? Do you need to vent at all the corners?
I think so, if the Pig is not level, or fuel is sloshing around there will be times when a vent line might be submerged in liquid and unable to relieve pressure or vacuum. It looks like a good design.
 
When I had the water tank built, the builder welded the baffles in all across the top of the tank and had holes at the bottom. That trapped air up into all three compartments and wouldn't let me fill it up completely with water. I had to vent each compartment and wasn't sure about the baffling in the stock tank. I have the 55 gal. aftermarket tank and it has four vents coming out of it.
I don't think the 4 vents does any harm! Just a few more lines to join up before going fwd to the charcoal can.
 
I assume that's to cover camber to either side with or w/o uphill or downhill slope. Hard to imagine though that you would find yourself in that situation for an extended enough period to actually pull a vacuum on the tank while under operation. I'm also assuming you need to keep it vented to both fill the tank and to also pull fuel out of the tank with the fuel pump while in operation?
This ^^^

If you see that ( baffle ) pick up is on the bottom of it , all other lines are on top of Baffle .hard to see but i cut tank right where that pick up is . ( I just cut and opps wrong spot to cut )

I am not totally following you Evan. Are you saying you were able to drill this hole and then unclog the fuel supply line?
How did you locate the intake from outside the tank?
Thanks!
Yes the hold drilled in the bottom of the tank was to drill out the pick up tube where it was spot welded to the floor of the tank . used a long drill bit , and then a flexible cable ( think speedo cable ) back through to the top . only the first 2 inches were plugged up

On a '71 the vents go to two emission tanks, one behind each cargo panel which then go to one line up to the charcoal canister. I eliminated the pass. side emissions tank and run all four lines to the driver's side emissions tank. I also have a GM fuel pump with a vent coming out of the top of the tank which ties into the line going up front to the charcoal tank. Spaghetti!
